Resumo |
Gold nanoparticles stabilized by amino-terminated ionic liquid (Au-IL) have been in situ noncovalently deposited on poly(sodium 4-styrene-sulfonate) (PSS)-functionalized multiwalled carbon nanotubes (MWCNTs) to form a MWCNTs/PSS/Au-IL nanocomposite. PSS can interact with MWCNTs through hydrophobic interaction. Amino-terminated ionic liquid was applied to reduce aqueous HAuCl4, and the resulting gold nanoparticles were attached to the PSS-functionalized MWCNTs simultaneously. Most gold nanoparticles dispersed well on the functionalized MWCNTs. Transmission electron microscopy, Raman and X-ray photoelectron spectroscopy were used to confirm the composition and structure of the nanocomposites. The resulting MWCNTs/PSS/Au-IL composite exhibits good electrocatalysis toward oxygen and hydrogen peroxide reduction. |
